    摘要： An apparatus includes, in some implementations, at least one image sensor, a plurality of metalenses, and readout and processing circuitry. The at least one image sensor includes pixel arrays, each of which is associated, respectively, with a different one of multiple optical channels configured for detection of incoming light rays of a respective color. The color for each optical channel differs from that of at least one of the other optical channels. Each of the metalenses is disposed, respectively, in a different one of the optical channels and is configured, respectively, to focus incoming light rays onto a different one of the pixel arrays. The readout and processing circuitry is operable to read out signals from the pixel arrays and to generate a respective lower-resolution image for each of the optical channels, and to process the lower-resolution images to obtain a higher-resolution multi-color image. Methods of operation are described as well.

    摘要： Structured light generating modules and systems are described. An example structured light generating module includes an array of discrete light sources, an array of discrete fanout elements, and an array of discrete collimator elements interposed between the array of discrete light sources and the array of discrete fanout elements. Each of the discrete collimator elements within the array of discrete collimator elements is aligned to a respective discrete light source within the array of discrete light sources. Each of the fanout elements within the array of discrete fanout elements is aligned to a respective discrete collimator element within the array of discrete collimator elements. Each of the respectively aligned discrete light sources, collimator elements, and fanout elements is configured to generate a unit-cell structured light illumination comprising one or more individual illumination features over at least a portion of a field of illumination of the structured light generating module, wherein one or more of the unit-cell structured light illuminations collectively are a structured light illumination.

    摘要： A method includes providing a coating (208) over a first surface (202) of a substrate (204) and over a metasurface (200) on the first surface of the substrate; and imprinting the coating to cause a surface of the coating to have a predetermined characteristic. A device includes a substrate; a metasurface on a first surface of the substrate; and a coating on the metasurface and on the first surface of the substrate, a surface of the coating defining a functional structure.
